--- Comment #2 from Chris Rankin rankincj@googlemail.com 2011-05-02 06:04:46 PDT --- Created an attachment (id=46250) --> (https://bugs.freedesktop.org/attachment.cgi?id=46250) FP debug output
Strictly speaking, this output is from RADEON_DEBUG=nohiz,fp because HiZ is also broken with M66GL chips at the moment.
